Background
In 1886, the first internal combustion engine powered automobile in the world was born, and the interior parts of the automobile were all made of traditional injection molding or coating materials, so that the automobile was single in appearance and lacked the feelings of vitality and science and technology. The concept of interior decoration is updated in 2009, and a large liquid crystal screen, an interior decoration atmosphere lamp and a starry sky ceiling appear, so that the idea is really applied in 2013.
However, when a general light-transmitting interior is used for an automotive interior, the following problems still exist:
1) the large liquid crystal screen is connected with the screen, so that the appearance is not attractive enough when the power supply is not switched on, and the traditional lack of science and technology and modern feeling are taken as the basis;
2) the interior decorative atmosphere lamp and other decorations are mostly made of PVC materials, and are difficult to meet the requirements on environmental protection;
3) traditional atmosphere discolours and decorates mainly to divide into two kinds, one kind is the decorative lamp area or the lamp strip of components of a whole that can function independently, and this kind not only environmental protection performance is general, and influences the pleasing to the eye of automotive interior daytime, and another kind is cloth art canopy or the atmosphere of moulding plastics is decorated, and these two kinds show the disappearance slightly in vision and sense of touch, and atmosphere decoration and operation are separately moreover, can not accomplish beautifully and use the coexistence.
